Postgraduate Study

The Institute of Astronomy offers the opportunity to study for the PhD degree, which is normally completed in three to four years. The format is almost entirely research-based, and while projects may be exclusively theoretical or observational, many combine aspects of both. Many projects incorporate aspects of Data Science, including machine learning and artificial intelligence.

Note: The university also offers a PhD programme in Astrophysics at the Cavendish Laboratory. For further information on this programme and details on how to apply please follow this link www.postgraduate.study.cam.ac.uk/courses/directory/pcphpdphy

It is normal for students to attend several relevant international conferences during their PhD, often presenting their own research work. Some students working on observational research projects undertake observing trips(s) to major international observatories.
